+Subject: [PATCH] usb-ehci: Fix an assert whenever isoc transfers are used
+
+hcd-ehci.c is missing an usb_packet_init() call for the ipacket UsbPacket
+it uses for isoc transfers, triggering an assert (taking the entire vm down)
+in usb_packet_setup as soon as any isoc transfers are done by a high speed
+USB device.
